双轮错距缩径旋压力测量平台设计

Design for measurement of spinning force on stagger neck-spinning with double rollers

为了提高加工效率,提出了双轮错距缩径旋压工艺。采用八角环测力计测量了旋压三向力,设计并通过理论计算验证了八角环测力计的准确性;通过应变分析,设计了应变片的贴片位置。在不同加工参数下,利用动态应变仪及八角环测力计对三向旋压力进行测定,对试验数据进行滤波处理,并最终得到三向旋压力的数据。

To improve the efficiency,stagger neck- spinning with double rollers is presented in this paper. An octagonal ring transducer is designed for measuring the spinning forces in three directions. The validity of the octagonal ring was verified by the theoretical calculations,and the positions of strain gauges were designed by strain analysis. The spinning force in different process parameters was measured by octagonal ring transducers and a dynamic stress- strain instrument. The data of forces was obtained after filtering.
